The Command line will prompt you to Specify Scale Factor. Set one of the following scale factors:. AutoCAD is technically a "unitless" system. For example, a line drawn from the coordinates 0,0 to 0,10 in Decimal Feet will be 10 "units" long.
Whether you change your units to inches, meters, millimeters, angstroms, or parsecs, the line will continue to measure 10 units. However, the issue of scale forces a new wrinkle into this perfect unitless world. If you did, in fact, change your units, you would eventually need the line to be measured in the number of your new units that match its measurement in the original units.
So for an object that was originally meant to measure 10 feet, changing your units to inches would then require the object to actually measure units in this case, inches, or 10 feet. The first value provides the decimal change. The second value provides the percentage that can be entered into a copier - a value larger than will make the drawing larger and a value less than will make the drawing smaller.
The Scale Converter requires iFrames to function and your browser does is not able to display iFrames; however, you can you can open the converter in a new browser window. Select the Profiles tab. Click Utilities Drawing Setup. Click the Units tab. Under Drawing Units, select the desired units. Various imperial and metric units are available. When prompted for scale factor, enter the appropriate scale factor for the units to be converted, based on the following:.
Type Scale command, Select whole Drawing then specify base point in any corner of drawing or point from which you want to scale. Then type Converting using a scale factor To convert from a scale drawing to real life, measure a line in the drawing and multiply it by the scale factor to find the real length. To convert from real life to a scale drawing, divide the real life measurement by the scale factor.
Suppose you are told that the smaller square has a side length of 2 inches and the scale factor from the smaller to the larger is 1 : 2. Remember, this means that 1 inch on the smaller square is 2 inches on the larger square. For figures which differ by a scale factor, the scale factor is the ratio of corresponding side lengths new image to old image.
